安装zookeeper集群

每台zookeeper都需要有下面的操作：

[root@localhost opt]# cd /usr/local

[root@localhost local]#rz -E #上传jdk

rz waiting to receive.

[root@localhost local]#tar -zxvf apache-zookeeper-3.6.4-bin.tar.gz #解压

[root@localhost local]#mv apache-zookeeper-3.6.4-bin zookeeper

[root@localhost local]# cd zookeeper/

[root@localhost zookeeper]# mkdir data #创建数据目录

[root@localhost zookeeper]# mkdir logs #创建日志目录

[root@localhost zookeeper]# ls

bin conf data docs lib LICENSE.txt logs NOTICE.txt README.md README_packaging.md

[root@localhost zookeeper]# cd conf

[root@localhost conf]# ls

configuration.xsl log4j.properties zoo_sample.cfg

[root@localhost conf]# mv zoo_sample.cfg zoo.cfg

[root@localhost conf]# vim zoo.cfg #修改配置文件

# The number of milliseconds of each tick

tickTime=2000 #通信心跳时间，zookeeper服务器与客户端心跳时间，毫秒

# The number of ticks that the initial

# synchronization phase can take

initLimit=10 #Leader和Follower初始连接时能容忍的最多心跳数（tickTime的数量），这里表示为10*2s

# The number of ticks that can pass between

# sending a request and getting an acknowledgement

syncLimit=5 #Leader和Follower之间同步通信的超时时间，这里表示如果超过5*2s，Leader认为Follwer死掉，并从服务器列表中删除Follwer

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

dataDir=/usr/local/zookeeper/data 修改，指定保存Zookeeper中的数据的目录，目录需要单独创建

dataLogDir=/usr/local/zookeeper/logs 添加，指定存放日志的目录，目录需要单独创建

# the port at which the clients will connect

clientPort=2181 #客户端连接端口

# the maximum number of client connections.

# increase this if you need to handle more clients

#maxClientCnxns=60

# Be sure to read the maintenance section of the

# administrator guide before turning on autopurge.

# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

# The number of snapshots to retain in dataDir

#autopurge.snapRetainCount=3

# Purge task interval in hours

# Set to "0" to disable auto purge feature

#autopurge.purgeInterval=1

# Metrics Providers

# https://prometheus.io Metrics Exporter

#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider

#metricsProvider.httpPort=7000

#metricsProvider.exportJvmInfo=true

#添加集群信息
